Question

Diffraction occurs for all types of waves, including sound waves. High-frequency sound from a distant source with wavelength 9.30cm passes through a narrow slit 12.0 cm wide. A microphone is placed 39.0cm directly in front of the center of the slit, corresponding to point O in the figure 36.5a in the textbook. The microphone is then moved in a direction perpendicular to the line from the center of the slit to point O. At what minimal distance from O will the intensity detected by the microphone be zero?

Explanation / Answer

sorry that was wrong wavelength this is the right one sin(angle)=m*wavelength/a m=1 wavelength=9.3 a=12 find the angle tan(angle)=Y/R R=39 Y=what you wats to calculate
